Intelligent fraud prevention
Unlike basic WAF or CAPTCHA solutions, Stytch Device Fingerprinting provides intelligent fraud prevention that protects your app while maintaining a frictionless end-user experience.- Integrate in minutes: Add a simple JavaScript snippet to immediately start monitoring vulnerabilities
- 99.99% accurate bot detection: The world’s most accurate device fingerprinting, leveraging standard and proprietary signals
- Invisible to real users: No clicking on stop signs or solving puzzles—only add friction to suspicious traffic
- <100ms latency: Frictionless UX with more than 3x lower latency than competing solutions
- Intelligent rate limiting: Granular device, browser, and network fingerprints go beyond IP address detection
- Tamper-resistant: Client-side encryption prevents reverse engineering and signal spoofing
- AI agent detection: Monitor, allow, or restrict AI-driven activity like OpenAI’s Operator and Anthropic’s Computer Use

Email risk
Detect disposable emails, typos, and suspicious email patterns.Coming soon
Fraud-proof auth flows
Seamlessly integrate fraud prevention into your authentication flows:Get started with Protected Auth
Automatically protect sign-ups and logins from account takeover attacks.
Remembered device detection
Recognize devices so users only need MFA when logging in from a new device.
Invisible CAPTCHA
Ensure delivery of email magic links even with enterprise security services.
New device notifications
Alert users when a new device login is detected for added security.
